Command Line Interface

Description:
  EvtxECmd version 2026.10.0

  Author: Eric Zimmerman (saericzimmerman@gmail.com)
  https://github.com/EricZimmerman/evtx

Usage:
  EvtxECmd [options]

Options:
  -f <f>           File to process. Either this or -d is required
  -d <d>           Directory to recursively process. Either this or -f is required
  --csv <csv>      Directory to save CSV formatted results to. Be sure to include the full path in double quotes
  --csvf <csvf>    File name to save CSV formatted results to. When present, overrides default name
  --json <json>    Directory to save JSON formatted results to. Be sure to include the full path in double quotes
  --jsonf <jsonf>  File name to save JSON formatted results to. When present, overrides default name
  --xml <xml>      Directory to save XML formatted results to
  --xmlf <xmlf>    File name to save XML formatted results to. When present, overrides default name
  --dt <dt>        The custom date/time format to use when displaying time stamps. See https://goo.gl/CNVq0k for options [default: yyyy-MM-dd HH:mm:ss.fffffff]
  --inc <inc>      List of Event IDs to process. All others are ignored. Overrides --exc Format is 4624,4625,5410,5500-5600
  --exc <exc>      List of Event IDs to IGNORE. All others are included. Format is 4624,4625,5410,5500-5600
  --sd <sd>        Start date for including events (UTC). Anything OLDER than this is dropped. Format should match --dt
  --ed <ed>        End date for including events (UTC). Anything NEWER than this is dropped. Format should match --dt
  --fj             When true, export all available data when using --json
  --tdt <tdt>      The number of seconds to use for time discrepancy detection. Default is 1 [default: 1]
  --met            When true, show metrics about processed event log. Default is true
  --maps <maps>    The path where event maps are located. Defaults to 'Maps' folder where program was executed
  --vss            Process all Volume Shadow Copies that exist on drive specified by -f or -d
  --dedupe         Deduplicate -f or -d & VSCs based on SHA-1. First file found wins
  --sync           If true, the latest maps from https://github.com/EricZimmerman/evtx/tree/master/evtx/Maps are downloaded and local maps updated
  --debug          Show debug information during processing
  --trace          Show trace information during processing
  -?, -h, --help   Show help and usage information
  --version        Show version information

Examples: EvtxECmd.exe -f "C:\Temp\Application.evtx" --csv "c:\temp\out" --csvf MyOutputFile.csv
          EvtxECmd.exe -f "C:\Temp\Application.evtx" --csv "c:\temp\out"
          EvtxECmd.exe -f "C:\Temp\Application.evtx" --json "c:\temp\jsonout"

          Short options (single letter) are prefixed with a single dash. Long commands are prefixed with two dashes

EvtxECmd exits with 0 when everything was processed, and 1 for bad arguments, a file that could not be processed, or output that could not be written.

Library

The evtx NuGet package parses event logs (MS-EVEN6 BinXml, including logs collected with Windows Event Forwarding, whose records have no templates):

using var fs = File.OpenRead(@"C:\Temp\Security.evtx");
var log = new evtx.EventLog(fs);
foreach (var record in log.GetEventRecords())
{
    Console.WriteLine($"{record.RecordNumber} {record.TimeCreated} {record.EventId} {record.Provider}");
    var xml = record.ConvertPayloadToXml(); //the event as XML
    var json = record.PayloadAsJson();      //EventData/UserData as JSON
}

foreach (var error in log.ErrorRecords) //records that could not be read, by record number
{
    Console.WriteLine($"{error.Key}: {error.Value}");
}

• Call EventLog.LoadMaps(path) first to fill PayloadData1-6, UserName, RemoteHost, ExecutableInfo and MapDescription from the maps.
• A file that is not an event log throws EventLogParseException. A damaged chunk or record is logged and skipped, and the rest of the log is still read.
• Records hidden in another record's slack (DanderSpritz's eventlogedit) are returned with HiddenRecord set.
• RenderingInfo holds the RenderingInfo element of forwarded events (the message text and level/task/opcode names from the source computer) as JSON.

Documentation

This project contains both the core parsing engine as well as a command line front end that uses it.
